Calcium metabolism and breast cancer risk
Emerging evidence suggests that calcium and its regulating hormones, i.e. vitamin D and parathyroid hormone (PTH), affect breast cancer risk. The associations between serum calcium levels and breast cancer risk, between serum calcium levels and known risk factors of breast cancer, and between serum …

Selenite influence on calcium metabolism of the rat lens
Calcium is an important factor in many cellular activities and in the maintenance of structural integrity of membranes. Calcium accumulation in the rat lens above the normal physiological range (0.11 µmol/g wet weight) has been associated with formation of cataracts. Selenite is known to influence …

Effects of copper on calcium metabolism and detoxification mechanisms in freshwater bivalve species of Anodonta
… Cu2+ effects on cellular plasma membrane calcium transport were studied first. In the second step, the investigations focused on Cu2+ detoxification mechanism involving cysteine (Cys) rich compounds known to play a major role in homeostasis of essential trace metals and in cellular metal …

The Effect of Long Term High Protein Induced Calciuria on Calcium Metabolism and Bone Status in Adult Rats
… of osteoporosis. The source of increased urinary calcium is controversial and has been attributed to either increased absorption, increased bone resorption or both. A 20 week study was conducted to determine long-term effects of various protein sources on calcium metabolism and bone status of 500 …

Effect of a Low-Carbohydrate, High-Protein Diet on Bone Mineral Density, Biomarkers of Bone Turnover, and Calcium Metabolism in Healthy Pre-Menopausal Females
… bone turnover, indicators of acid-base balance, calcium homeostasis and fasting lipids in healthy pre-menopausal women was conducted. Women, aged 32 - 45 y, with a body mass index between 25-41 kg/m2 were randomized into one of two diet groups: LCHP (n = 13) or high-carbohydrate, low-fat (HCLF) …

Use of polyhalite mineral as an acidogenic product in the diets of close-up non-lactating dairy cows
… the urine pH, dry matter intake, milk yield, and calcium and magnesium concentration of urine and serum in pre-partum and non-lactating dairy cows consuming diets containing a low dose of polyhalite (200 g/cow/day), a high dose of polyhalite (400 g/cow/day), calcium chloride (250 g/cow/day), or no …

Functional characterization of a putative Plasmodium falciparum calcium/hydrogen antiporter pfcha
… of essential genes are needed. Although the calcium metabolism is very important in the life of P. falciparum, little is known about the genes which regulate the transport of calcium. With the release of the P. falciparum genome, a putative calcium hydrogen antiporter has been identified. To …

Altered bone metabolism in the protein deprived rat
… as the 1920's it was realised that the skeletal metabolism in protein-calorie malnutrition was deranged. Notwithstanding this, there is still to date inadequate understanding of the mechanisms by which these skeletal changes are brought about. This is partly due to the fact that the research …

Effects of magnesium and calcium upon excitation-contraction coupling in the heart
Calcium (Ca2 ) availability to cardiac myofilaments is the primary factor determining the force of cardiac contraction. An intracellular organelle, the sarcoplasmic reticulum (SR), regulates the relaxation of the muscle as well as acting as a source of activating Ca2 during excitation-contraction …

Mechanisms of Calcium Buffering and Aging in Neurons: Testing the Limits of Homeostasis
<p>Intracellular calcium ([Ca<sup>2+</sup>]i) is an ubiquitous second messenger that integrates multiple and diverse neuronal pathways that include development and maturation, gene expression, synaptic plasticity, transmitter release, excitability, and even cell death. Upon neuronal excitation the …
